My experience - hope it helps someone

My 4 months 81 300 SD was starting to show signs of losing power going uphill. Some slopes I used to climb @70mph, car was just dying. There was definitely fuel starvation. Transmisson was also flaring under heavy acceleration, especially 2 to 3 shift.

I decided to fix the problems one at a time. I replaced both fuel filters and guess what happened, that fixed BOTH problems! How is that?

I however can see fuel slowly leaking from the edges of the big bolt. I replaced the o-ring on the bolt but not the washer, I'm thinking I might have to because it looked pretty bad. I have tightened the bolt as much as I think I should, am I doing something wrong?

Thank you all.

No. Those aluminum gaskets are soft and can only be reused so many times. Which is not to say that they should ever be reused.

I will probably have to replace the bolt and the washer next time I change the large fuel filter, as it was seeping a little after I recently changed the filter, so I tightened it extremely tight and now there's not so much as a drop, I did mess up the bolt's head a bit though....I'll just replace it next time.....which is probably about 1-2 years away, so no big deal.

Soft metal washers, i.e. al. or copper, should ALWAYS be replaced once they have been opened. These metals work harden when they are tighened and often will not seal well when reused.

If you don't have new washers but do have a propane torch you can hang the copper washers on a piece of wire, heat them until they glow red and then quench then fuickly in water. That will soften them back to their original state and you are good to go. This might work for al. washers but because al. doesn't change color with temp. it is difficult to tell when they are hot.

Life is full of suprises. Went back to the dealer and talked to the same guy who sold the 2 filters and the o-ring. Told him I wanted the other stuff and one of those fuel filter bolt washers because it was leaking after the filter change. He then remembered that when I was there earlier, I asked him to give me everything I needed for fuel filter changes. I even asked him about the washer but he did not include it, he just gave me the o-ring. He went away for a minute then came back with his boss and they gave me the washer for free. I know it does not cost a lot of money but I was pleasantly surprised.
